        WebSettings settings = mWebView.getSettings();
        settings.setJavaScriptEnabled(true);//启用js
        settings.setBlockNetworkImage(false);//解决图片不显示
        if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP) {
            settings.setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
